Product Description

Product Description

Plasma waste gas treatment, solid waste treatment electrode
1. Waste gas treatment
Plasma technology can be used in waste gas treatment, water treatment, etc., such as converting harmful substances in waste gas into harmless substances, or oxidizing and decomposing organic matter in waste water. It can be used not only in the treatment of industrial waste gas, but also in indoor air purification, water treatment, food safety, medical equipment disinfection, hospital air purification and other fields to provide people with a healthier and safer environment.
2. Solid waste treatment
At present, when plasma technology is used to treat solid pollutants (waste) at home and abroad, the main type of plasma used is thermal plasma. Thermal plasma is used to treat solid waste. The treatment methods can be divided into the following types:
(1) plasma oxidation, combustion or plasma vitrification;
(2) plasma pyrolysis, which makes combustible solid waste in reducing state Gasification in the atmosphere and recombination into other gases:
(3) Pulse arc generates shock waves, which are used to decompose and separate solid waste into metals, plastics, organic matter, etc.
    Among them, the wastes that use plasma high temperature and high enthalpy for plasma oxidation, combustion or plasma vitrification to achieve degradation and volume reduction are mainly construction waste, urban sludge, waste incineration residue, urban garbage, and medical waste. Plasma pyrolysis technology is applicable to all the above-mentioned wastes, and generally produces syngas, which is used in combustion, fuel cells, etc. The use of pulse arc to generate shock wave plasma is generally suitable for the simultaneous collection of materials from construction waste and waste electronic products.
3. Plasma waste gas treatment and solid waste treatment electrodes
    The plasma exhaust gas treatment electrode produced by our company is a technical equipment used to treat harmful substances in exhaust gas. It uses plasma technology to convert harmful substances in exhaust gas into harmless substances through high temperature, high pressure and electric field to achieve the purpose of purifying exhaust gas.
Plasma exhaust gas treatment electrodes are divided into anodes and cathodes. By generating plasma between the anode and cathode, harmful substances in the exhaust gas can be effectively converted into harmless substances. In addition to providing electric fields and currents, electrodes also need to have good electrical conductivity and corrosion resistance. Because during the plasma waste gas treatment process, the electrodes will be affected by factors such as high temperature, high pressure, and chemical erosion. Therefore, the material selection and manufacturing process of the electrode are very important.

Our Advantages

Advantages of plasma electrodes produced by our company:
1. Our company has been engaged in the production of pure tungsten and tungsten alloy materials for many years, and has an in-depth understanding of the structure and properties of materials. For the tungsten electrode used in plasma spraying electrodes, based on our full understanding of the application, we have made more improvements and treatments to the material structure to meet the material requirements of plasma spraying. By densifying the tungsten electrode, a finer, more uniform grain structure is formed. The modified tungsten alloy has relatively high hardness and density, fast arc starting, excellent resistance to arc burning loss, and long life.

2. Our company's plasma spraying electrodes and nozzles use unique back-casting technology to achieve seamless bonding between tungsten and copper. The bonding strength can be as high as 127MPa, while the traditional bonding strength is less than 100MPa. Compared with traditional brazing, joints made by back-casting have higher bonding strength between tungsten and copper, larger contact area, more uniform resistance, and stronger heat dissipation ability, making the nozzle and electrode more stable and more durable as well as long service life.

3. We produce tungsten electrodes of different materials (good arc starting performance and ablation resistance). Based on customer usage conditions, we can provide more suitable materials for customers to choose.
 

Material	Impurity content (%)	Electron work function (eV)
Lanthanum tungsten	<0.2	2.8-3.2
Cerium tungsten	<0.2	2.7-2.8
Thorium tungsten	<0.2	2.0-3.9

4. Based on the research and analysis of plasma spray guns, the electrodes and nozzles produced by our company can perfectly adapt to the original spray guns, and no additional adjustment of spraying parameters is required during replacement. We have a complete product series, and the plasma spray electrodes and nozzles we produce can be widely used in F4, 9M, SG-100 and other spray guns of Metco, GTV, FST, AMT AG, Praxair and other companies.
5. We have rich experience in producing various cathodes and anodes, which can be customized and processed according to customer samples or drawings. We can also provide semi-finished products with seamless combination of tungsten and copper.

 

In a nut shell,our plasma electrode has the advantages as below:

1,Strong corrosion resistance
2,long life
3,Good thermal conductivity
4,Good electrical conductivity etc.

After Sales Service

 

We can ensure our all products which are seamless bonding,no gas foam generating,and assure concentricity,if any defect has been found which are due to our cause,we can replace them for free and send you along with shipment for next time.
